I am writing to find out whether you are growing 'Green Tower' Boxwoods right now, what height they are and if they are available for purchase? I've have contacted my local Armstrong Nursery in San Juan Capistrano and they aren't itemized on their list. Therefore, they don't think they are available. I live in south orange county. Is there any other nursery that I could purchase them from? Finally, we need quite a few of them (35) as we are intending to create a screen on one side of our house. Any help you could offer with this plant would be most appreciated.

Green Tower is a new Monrovia introduction and it is definitely in production. Retailers order independently so not all nurseries will carry every Monrovia plant. However, I've located 3 nurseries in your general vicinity that appear to have Green Towers in stock:
